spring integration-mqtt type converter issue - spring

Question

Trying to run the sample spring-integration mqtt project from web.
I have imported the mqtt-context in root context. After the war is deployed I am running the RunMqtt.java file. But getting the following issue. If running in standalone mode , the same file does not give any issue.

Answer 1

the sample spring-integration mqtt project
Which sample?
Please show your configuration.
EDIT:
It looks like Spring is having trouble determining which constructor to use.
Try adding
<bean id="clientFactory" class="org.springframework.integration.mqtt.core.DefaultMqttPahoClientFactory" />
and add client-factory="clientFactory" to the message-driven adapter.
